Application of Single Chip Microcomputer Based on I/O Mode to Intelligent Uninterrupted Power System

采用基于 I/ O方式的内部自带 OTP(Only time programing) ROM中的单片机 ,既能满足智能化要求 ,又能大大节约 UPS的生产成本。文中介绍了基于 I/ O方式下单片机在线互动式不间断电源中的典型应用 ,阐述了采用 GMS系列具有 OTP型 ROM的单片机为微控制器 ,配以串行方式的接口芯片构成 UPS主控系统的组成及工作原理。着重介绍单片机与串行芯片及模拟串行方式的接口方法 ,以及基于 I/ O方式下单片机应用系统的设计思想。实践证明 。

It is very important for the application of UPS(Uninterrupted power system) with intellectualized far distance interface. It meets the need of intelligence, and saves large cost of producing UPS, by using single chip microcomputer including OTP(Only time programing) ROM inside it is based on I/O working mode. The typical application of single chip microcomputer based on I/O mode to intelligent on line interactive UPS is introduced. The main control system′s construction and principle of microcontroller are expatiated by using GMS series single chip microcomputer with OTP ROM which provides interface chip having serial interface mode. A method of interface between microcontroller and chip with serial data transfer, and the technique of simulating serial data transfer is emphasized. Design idea of application system of single chip microcomputer based on I/O mode is proposed. It shows that the method has great practical value.
